Hi everybody, My girlfriend and I was riding and made a stop, I noticed gear oil leaking out of the right side of the wheel. I looked at the fill plug and noticed it is leaking from the top side apprx 4"-5" above the fill plug. It looks like there is a cap I cant get off. Is it possible the cap is leaking? and if so can it be a easy fix??? Thanks

Yeah thanks, I went out and pulled the filler bolt and about 1oz of gear oil came out, I looked @ my Haynes book and found it only needs to be at the bottom of the hole. I just got back after taking another ride and is not leaking anymore. Thank you for the input. Have a good one...

Like Dusty said, this is commonly caused by filling the rear end when the bike is on the side stand instead of the center stand, which causes it to become overfilled. It froths up inside, and blows out the vent as a result. You've already fixed the problem now.
